Tools
Agent readiness tools
Each checker here runs the full scan, and the report opens on the checks it names. The generator writes robots.txt lines and sends no request.
Crawlers and files
-
llms.txt checker
Check /llms.txt and /llms-full.txt the way an agent reads them. Each result shows its evidence, any change to make, and a command that repeats it.
-
AI crawler checker
See which AI crawlers your robots.txt names, what it allows each one, and whether it states Content-Signal preferences. Each result shows its evidence.
-
AI robots.txt generator
Build robots.txt lines that block AI crawlers by purpose: training, search, or fetches a user asks for. It sends no request, and allowed crawlers stay unnamed.
Agent interfaces
-
MCP server tester
Find the MCP server your site names and open one session with it. The scan sends initialize and tools/list, calls no tool, and shows the tools it lists.
-
WebMCP checker
Find the WebMCP tools your homepage declares: registerTool() calls and forms with a toolname. The scan reads the HTML it is served and runs no JavaScript.
-
OpenAPI checker
Find the OpenAPI document, API catalog, docs, and OAuth metadata a site publishes, and check each one. It reads what the site serves, not a pasted file.
HTTP
-
Markdown for agents checker
Ask your homepage for markdown the way a coding agent does, and see the type and Vary header it answers with. Each result shows its evidence.
-
HTTP cache checker
Test the cache headers of your homepage and whether it answers a validator with 304. See what a missing page answers to a browser and to a JSON client.
Every checker sends the scan the scan form sends, with the same limits. The 60 checks lists the rest of the rubric.
